RAILWAY SIGNALING SYSTEM.

Specification of Letters Patent.

Original application filed February 1, 1910, Serial No. 541,330. Divided and this application filed July 29,

Serial No. 574,483.

To a VJJ/LU'HP/ it may concern Be it known that I, Anri-ronsn Bronx, a citizen of the United States, residing at Nashua, in the county of Hillsboro and State of New Hampshire, have invented certain new and useful Improvements in "tailway Signaling Systems; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in railway signaling systems, and particularly to means for giving an alarm when the s gnaling system is disabled or partially dlsabled.

The object in view is the arrangement of a signaling system, including line wires, associated with means for automatically indicating at stations along the track or moving trains when the system is disabled to any extent.

A further object of the invention is the arrangement in combination with a track signaling system, of means for signaling stations along the track when the track signaling system is out of order.

A still further object of the inventlon more specifically is the arrangement of a system of signaling for railways, 1n which a trolley wire is used, and a station wire, together with means for indicatlng at stat ons along the track whenever one of the wires has been broken and the system thereby crippled.

\Vith these and other objects in view the invention comprises certain novel constructions, combinations, and arrangement of parts as will be hereinafter more fully de scribed and claimed.

In order that the invention may be more fully understood an embodiment of the same is shown in the accompanying drawings, in which- In the accompanying drawings: Figure 1 is a diagrammatic view showing. a track signaling system, and means for indicating when the same has been disabled. Fig. 2 is an enlarged detail side elevation of the mechanism used for signaling stations along the track when the system has been crippled. Fig. 3 is an enlarged detail top plan view of a. three pole push button embodying certain features of the invention. Fig. 4.- is a section through Fig. 3, approximately on line 1- 1.

In constructing or establishing a system for signaling trains on the track, and ncans for indicating that the same has been disabled, a trolley wire is mounted over the track or near the same, and parallel therewith. The various engines traveling over the track are provided with means for communicating with said trolley wire, and in the event of the trolley wire breaking there is a medium of notifying the responsible persons of a train or depot as to the conditions, and an auxiliary wire thrown into circuit.

1 and 2 indicate the rails of the track which are divided into blocks or sections 3, 4t, 5, 6, 7, S and 9 by insulations 10. These sections or blocks are arranged in staggered relationship to each other, so that the insulations 10 on rail 1 will be midway between the insulations 10 on rail 2. Arranged above, and if desired to one side of the track, is a trolley wire 11 supported by any desired number of supporting poles 12. Trolley wire 11- is designed to carry only sutlicient current for operating the various signals, and is not used for providing propulsion current. Trolley wire 11 extends for the full length of the signaling system, and is connected by wires 13 to the respective stations 14 arranged at any desired distance along the track. Wire 13 of station 14; is connected with bell 15 so that when trolley wire 11 breaks current may flow through hell 15 to battery 16, wire 17, station wire 18, and one of the lovers 19 and 20 and associated mechanism. WVhen trolley wire 11. breaks at the point indicated as A, Fig. 1, levers 19 and 20 of the adjoining poles 12, drop down by gravity. The levers 19 and 20 which are electrically and rigidly secured to trolley wire 11 maintain their contact therewith and move upon their pivotal points 21 and 22 until the extensions 23 and 2 1 depress or close the switches 25 and 26. This will connect station wire 18 and trolley wire 11 on each side of point- A, so that the stations on each side of the break will be notified.

When lever 19 moves downward and closes switch 25, the current will flow as follows: Commencing with battery 16 the direction of flow will be, for instance, through wire 17, station wire 18, wire 2'7, contact 39, contact 10, wire 12, extension 28, lever 19, trolley wire 11, wire 13, and through hell 15 back to battery 16. On the opposite side of the break to station 14: the

to battery corresponding station will be signaled, and the current will flow substantially in the same manner as traced, except through the opposite wiring and associated parts, including lever 20. This means for indicating whenever trolley wire 11 is broken is associated with the various wirings and device for signaling trains 324C and 325, and is used for signaling these trains whenever the same enter any of the sections in which a break in trolley wire 11 occurs. If trolley wire 11 were broken at A, Fig. 1, not only would bell 15 be sounded, but also bell 28 on engine 325. The sounding of bell 28 would commence as soon as engine 325 had passed the insulation 10 and entered on section t. As soon as engine enters on section 1 current will pass from battery 29 on engine 325 to bell 28, trolley pole 30, trolley wire 11, lever 19, extension 23, wire 42, contact 40, contact 39, contact 38, wire 31, wire 32, track section i, and from thence to the axle of the wheels of engine 325 back to the battery. The bell 28 will ring continuously until the break has been repaired or the engine has passed off of section at.

Associated wit-h levers 19 and 20 is a lever 34 which, together with the associated mechanism, is arranged to ring bell 15 when station wire 18 is broken, but does not ring either of the bells 28 or 33. The station wire 18 is supported by suitable brackets carried upon supporting poles 12, and in turn supports or carries the respective levers 3st. In arranging levers 3% one lever is provided between each pair out poles 12, so that wire 18 cannot be broken at any point without permitting one of the levers 34 to drop. If wire 18 should break at the point indicated at B on Fig. 1, lever 3st will imme diately drop and press button 35 of switch 35. Connected to one of the poles of the switch 35 is a wire 36 whichis, secured to station wire 18 on the opposite side of pole 12 to lever 34. Connected to the other pole of switch 35 is a wire 37 connected to the trolley wire. By this arrangement whenever lever 34 drops and closes switch 35 a circuit is established, so that current will flow from battery 16 through wire 17, station wire 18, wire 36, switch 35, wire 37, trolley wire 11, wire 13, bell 15, and back Switch 35 is of the ordinary two pole type and is intended to connect only wires 36 and 37, but buttons 25 and 26 are specially constructed and formed with three poles. The three pole switches 25 and 26, as more clearly shown in Figs. 3 and 4c, are provided with suitable housings having spring contact members 38, 39 and 40. A suitable button ll is also provided for contacting-with the movable parts of levers 19 and 20. Contacts 38 and 39 are connected with wires 31 and 27, while contact 40 is connected with wire 42 which is secured to levers 19 and 20.
